I must say this was a very brave under taking. I truly love the WHAT-IF approach, it gives a much better option. I have have had a similar idea that started in 2008. After buying a Gato 1/72 scale Submarine.....I started looking for a great Subject to base it on - Came across the story of Operation of attack on Truk Atoll. Where a Balao Submarine USS Tang rescued a bunch of Aviators off Truk during the battle.
Well the idea as what does with modelling got out of hand. I eventually came up with a concept WHAT-IF - What if Germans somehow came to the ''rescue'' of Truk Atoll Base and the entire Atoll became a massive Fortress. With quite a few of the Luft '46 plus Japanese futuristic Weapons being produced on the various Islands.
So coming back to your amazing concept - I think this is a stunning idea.
Personally I believe the main reason that you are not getting any modellers support is because very few modellers actually can imagine a true WHAT-IF Concept.
I suggest posting your article on this Forum as well
